ROLLER-BEARING HANGERFBOX.

Specification of Letters atent,

Patented Urt. 27, i914.

T0 all whom it may concern:

Be it known that I, CHARLES S. Looiwoon, a citizen of the United States, residingr at 289 Market street, Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Roller- Bearing Hanger-Boxes, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to a hanger-box to contain anti-friction rolls for supportinpr a rotating shaft, such rolls being usually accompanied by a cage which holds the rolls together before insertion in the hangenhox. and which guides them when placed therein by Contact with flanges at or near opposite ends of the box.

The invention is especially applicable to what are termed solid boxes into which the shaft lnust be inserted endwise;

The object of the invention is to furnish a construction for such a roller-hearing hanger-box by which no rivets, welds, or other fastenings are required to make the box complete for use in a hanger, and this object is attained by forming a central sad- 'dle with bore adapted to receive a sheetmetal casing, by pressing or screwingr the casing into the saddle. The rolls rotate directly within such sheet-metal casing.

The complete structure embraces a shell having a collar forced within each end and carrying a spring-wiper-block to kecp oil from working out. of the casing, each collar having an annular flange to guide the adja cent end of the roll-cage. The end of the Casin may be, formed with integral inward y turned flanges by making th(` casing of two sheet-metal shells open at their inner ends into which a cage containing a set ot rolls can be inserted, the open ends of the shells being fitted into contiguity within the saddle, by pressing or .screwing them therein.

To avoid possibility of any displacement of the shells within the saddle, an oil-hole bushin may be screwed through the side of the sa dl into a hole formed in the shell. In the case of a threaded shell this prevents the rotation of the shell, and in case of one merely pressed into the saddle, it prevents any tendency to loosen or escape.

The invention will be understood hv rel'- erence to the annexed drawing. in whichm4 Figure l an elevation of the hearing. in section where hatched, at the ccntcr line ot' they casing; Fig. 2 is an end view ol' the hearing: Fig. 3 is a side view of thc saddle: Fig. 4 is a section on line lvl in Fig. l: Fig. .3 is a section` like the upper part of Fig. 1, showingf shells merely pressed into the saddle; Fig. (i is a side view o'l' om` ot' the shells; and Fig. T is a transverse section of one of the oil-wipers and its supportingr parts.

The saddle is shown as a suhstantialli1 cylindrical huh f1 havin;r ilat .seats l at opposite sides to fit the legs of the hanger. and spherical bosses c upon thc upper and lower sides which may bc titled to .splicrical sockets in the hanger: but such bosses nrc Shown with central sockets by which thc hanger-box can be supported upon thc points of" set-screws in the. usual manner.

In thc hanger-box illustrated in Fig. l, the saddle isbored in its ends to lit snngly the exterior ct the shells my, and in its niid die portion is fornicd with scrcw-thrcznl f adapted to til a thread j" upon the inncr cnd of each shcll. The outer ends of thc shells are formed with inwardly bent oil-retaining ilanges adapted to clear the shaft and be open at their inner ends. such open ends beingr forced into close contact with one another when they are screwed into the saddle.

A collar e is shown iittcd within cach shell contiguous to the ilange l1. hcintr tittcd tightly therein so as to positivcly rctain its location. Ilach collar foi-mcd at ils inncr cnd with a lal tlangfc'c'. and the cages i. which carry thc rolls rctatc closil to the flanges c which guide thcni and hohl thcin in place. 'l`he space betwccn thc llangcs r and z forlns n wipcr-chan1hcr le. and the space between thc two llangcs x torn. the

roll-space in which thc rolls rotate around the shaft in direct Contact with thc interior of the shells.

The cages and rolls are inserted in tho open ends of thc shells before they are fitted into thc saddle, and are prrn'mrtioncd so that the heads ot this cages adjacent the joint of the two shells revolve close to one another, the two cages and sets of rolls titting loosely between the flat flanges t near the opposite ends of the easing.

Oil-hole bushings are shown in lig. l crewed through the wall of the saddle and the inner end projected into a hole in the shell which iii/:limited at Z in Fig. The eollars e are inserted chiefly to carry oilwipers. which rub eoi'itinuouslfv upon the shaft close tothe end-flziuzges z. o the hangerboX. ,Such oil-wipers are shown in Fig. 7. @insisting ot' a wiper-bloel m tittel mov ably in :t socket n which is pressed into a hole in the collar e and forced normally outwe rd by a spring o. The Wiper-block is pro vided with an enlargement m upon its inner end. which permits; it to move as far the .surfaee of' the shaft but not to Inoieet nia teriallyv beyond that line. as it would interfere with the endwise insertion ot' the shaft in the hangenbox.

Fig. shows the upper part of the saddle in. section with bore extendingl straight through. and the inner ends ot' two shells forced therein and held from displacement only by the oil-hole bushings By proper workmanshni. such shells mayy be pressed tightlyl into the bore ot' the sfn'ldle and the rollars e tightl)7 pressed within the opposite. ends of the shells to carry the oilfwipers. so that the union of the Ashells with the saddle and the union of the oil-wipers and the gfuideflanges c is effected without rivets, ,zelds, or other such fastenings.

The oil is supplied to the bearing through the oil-bushings le, so that in practice the rolls are fully bathed with the oil, and the oil thus conveyed to the shaft is prevented from working outside of the endlanges l1 hy the constant rubbingr of the oil-wipers lightly against the peri hei-'v of the shaft. which removes the oil tl'ierefroln and leads it downward into the chambers between the flanges e and la. From such chamber it escapes again into the roll-space through onelor more holes c* formed in the llanges e' adjacent to the oilwviper.

The structure is adapted to be infidewholly by pressing and drawing the parts from sheet-metah exeepting' the rolls and the saddle, and the boxes eau thus be mann fai-lured with great eheapness. and with entirely interchangeable parts.

The oil-wiper is made separate from the collar e and held therein by a head e5, when the collar is forced into the shell.

lt will be understood from the above, that the saddle or Central hub of the hanger-box is made in one piece, and may be termed a one-piece saddle, and thaty the casing when l l l l l l l l l l l l l, l

formed of two shells may be termed a two piene eaeing.

Having thus sei. forth the nature of rifle invention what is claimed herein ist l. ln a roll rbearingr hangenhox. the combination, with a saddle suitably bored to receive a easing, of a sheetmetril easing made in two shells each having en oilre taining flange at its outer end and, being open at its inner end, and such inner endi fitted in eontiguity within the 2. lx: :i rolierdwar fui: eoinbination, w ith oiif'f-}=ie ci Y in its ends Qmootl sections vsind h er niilldh potion lli WU :l-Ulir`r haiingfy a screw' severing the .sholle in @on saddle.
